Host controller interface (USB, Firewire) – Wikipedia
Intel hosted EHCI conformance-testing and this helped to prevent the incursion of proprietary features. On the expansion card or motherboard controller, this involves much custom logic, with digital logic engines in the motherboard’s controller chip, plus analog circuitry managing the high-speed differential signals. EHCI was designed [ by whom? This page was last edited on 17 Januaryat From Wikipedia, the free encyclopedia.

Because the card has a standard OHCI interface, the OS does not need to know in advance exactly who makes the card or how it works; it can safely assume that the card understands the set of well-defined commands that are defined in the standard protocol.

CONFIG_USB_EHCI_HCD: EHCI HCD (USB 2.0) support
The OHCI driver provided ehvi and full-speed functions for USB ports of a PCI expansion card with any other chipset vendor’s integrated USB host controllers or discrete controller chipsets attached to the computer’s expansion bus, if present.
The driver software is typically provided with an operating system of a personal computerbut may also be implemented by application-specific devices such as a microcontroller. Extensible Host Controller Interface xHCI is the newest host controller standard that improves speed, power efficiency and virtualization over its predecessors.
